According to Turner & Gustafson (Wildflowers of the Pacific Northwest), this groundsel relative is found mostly in California, and is rare in central and southern Oregon. Found exclusively at high elevations in dry, rocky, open areas such as the middle and lower edges of Collier Cone, a 1500 year-0ld cinder cone near the base of North Sister. The genus name comes from Laurent Railliard, an officer on the voyage of Louis de Freycinet in 1817-1820. Argentea is latin for “silvery”.
